This article will guide you through the process of adding these fields, enabling you to collect specific data directly from your customers during checkout.
Main Part: Adding Custom Fields to WooCommerce Checkout
There are several ways to add custom fields to your WooCommerce checkout page. We’ll focus on using code, which offers the most flexibility, but we’ll also mention plugins as an alternative.
1. Understanding the WooCommerce `woocommerce_checkout_fields` Filter
The core of adding custom fields programmatically lies in the `woocommerce_checkout_fields` filter. This filter allows you to modify the existing checkout fields and add new ones. You’ll need to add code to your theme’s `functions.php` file or a custom plugin. Always back up your website before making changes to your theme’s files.
2. Adding the Code Snippet
Here’s a code snippet you can adapt to add your custom fields:
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
$fields[‘billing’][‘custom_billing_field’] = array(
‘label’ => __(‘Your Custom Field Label’, ‘woocommerce’),
‘placeholder’ => _x(‘Enter something here’, ‘placeholder’, ‘woocommerce’),
‘required’ => true, // Set to true if the field is mandatory
‘class’ => array(‘form-row-wide’), // CSS class for styling
‘clear’ => true
);
return $fields;
}
Explanation:
- `add_filter( ‘woocommerce_checkout_fields’ , ‘custom_override_checkout_fields’ );`: This line hooks your custom function `custom_override_checkout_fields` into the `woocommerce_checkout_fields` filter.
- `$fields[‘billing’][‘custom_billing_field’] = array(…);`: This creates a new field within the ‘billing’ section. You can also use `shipping` for the shipping address section. `custom_billing_field` is the unique identifier for your field.
- `’label’ => __(‘Your Custom Field Label’, ‘woocommerce’),`: Sets the label that appears next to the field. Use a descriptive label.
- `’placeholder’ => _x(‘Enter something here’, ‘placeholder’, ‘woocommerce’),`: Provides placeholder text inside the field to guide the user.
- `’required’ => true,`: Makes the field mandatory. If set to `false`, the customer can proceed without filling it in.
- `’class’ => array(‘form-row-wide’),`: Adds CSS classes for styling. WooCommerce provides classes like `form-row-wide`, `form-row-first`, and `form-row-last` to control the width and positioning of the field.
- `’clear’ => true`: Adds a `clear: both` style to the field, ensuring it clears any floats.
- `return $fields;`: Returns the modified array of fields.
- `text`: A standard text input field.
- `email`: An email input field.
- `tel`: A telephone number input field.
- `select`: A dropdown select field.

- `checkbox`: A checkbox.
3. Available Field Types
You can specify the type of field using the `’type’` key within the field array. Some common field types include:
Example of a Select Field:
$fields['billing']['custom_billing_select'] = array( 'label' => __('How did you hear about us?', 'woocommerce'), 'required' => true, 'class' => array('form-row-wide'), 'clear' => true, 'type' => 'select', 'options' => array( '' => __('Select an option...', 'woocommerce'), 'google' => __('Google Search', 'woocommerce'), 'friend' => __('From a Friend', 'woocommerce'), 'social' => __('Social Media', 'woocommerce'), 'other' => __('Other', 'woocommerce') ) );
4. Saving the Custom Field Values
The next step is to save the data entered by the customer. Use the `woocommerce_checkout_update_order_meta` action hook.
add_action( 'woocommerce_checkout_update_order_meta', 'custom_checkout_field_update_order_meta' );
function custom_checkout_field_update_order_meta( $order_id ) {
if ( ! empty( $_POST[‘custom_billing_field’] ) ) {
update_post_meta( $order_id, ‘_custom_billing_field’, sanitize_text_field( $_POST[‘custom_billing_field’] ) );
}
if ( ! empty( $_POST[‘custom_billing_select’] ) ) {
update_post_meta( $order_id, ‘_custom_billing_select’, sanitize_text_field( $_POST[‘custom_billing_select’] ) );
}
}
Explanation:
- `add_action( ‘woocommerce_checkout_update_order_meta’, ‘custom_checkout_field_update_order_meta’ );`: Hooks your function into the `woocommerce_checkout_update_order_meta` action.
- `if ( ! empty( $_POST[‘custom_billing_field’] ) ) { … }`: Checks if the custom field was filled.
- `update_post_meta( $order_id, ‘_custom_billing_field’, sanitize_text_field( $_POST[‘custom_billing_field’] ) );`: Saves the value of the custom field as post meta for the order. Important: The `sanitize_text_field()` function is crucial for security, preventing malicious code from being saved. Adapt the sanitization function to match the field type (e.g., use `sanitize_email()` for email fields). The `_custom_billing_field` is the meta key used to retrieve the value later. It’s best practice to prefix meta keys with an underscore (`_`) to indicate that they are private or internal.
5. Displaying the Custom Field Values
Finally, you’ll likely want to display the custom field values in the order details page in the WooCommerce admin. Use the `woocommerce_admin_order_data_after_billing_address` or `woocommerce_admin_order_data_after_shipping_address` action hook.
add_action( 'woocommerce_admin_order_data_after_billing_address', 'custom_checkout_field_display_admin_order_meta', 10, 1 );
function custom_checkout_field_display_admin_order_meta($order){
echo ‘
‘.__(‘Your Custom Field’, ‘woocommerce’).’: ‘ . get_post_meta( $order->get_id(), ‘_custom_billing_field’, true ) . ‘
‘;
echo ‘
‘.__(‘How did they hear about us?’, ‘woocommerce’).’: ‘ . get_post_meta( $order->get_id(), ‘_custom_billing_select’, true ) . ‘
‘;
}
Explanation:
- `add_action( ‘woocommerce_admin_order_data_after_billing_address’, ‘custom_checkout_field_display_admin_order_meta’, 10, 1 );`: Hooks your function into the `woocommerce_admin_order_data_after_billing_address` action.
- `echo ‘
‘.__(‘Your Custom Field’, ‘woocommerce’).’: ‘ . get_post_meta( $order->get_id(), ‘_custom_billing_field’, true ) . ‘
‘;`: Retrieves the custom field value using `get_post_meta()` and displays it. Remember to use the same meta key you used when saving the value.
6. Using Plugins (Alternative Method)
If you’re not comfortable coding, several plugins can help you add custom fields to your WooCommerce checkout. Some popular options include:
- Checkout Field Editor (Checkout Manager) for WooCommerce: A free and popular plugin with a user-friendly interface.
- WooCommerce Checkout Field Editor Pro: A premium plugin with advanced features like conditional fields and field validation.
Pros of using plugins:
- Easy to use: No coding required.
- Pre-built features: Often include features like conditional logic and validation.
Cons of using plugins:
- Potential for conflicts: Can conflict with other plugins or themes.
- Overhead: May add extra weight to your site.

7. Considerations and Best Practices
- Data Privacy: Be mindful of data privacy regulations (like GDPR) when collecting customer information. Clearly explain why you need the information and how you will use it.
- Keep it Simple: Only add fields that are absolutely necessary. A long and complicated checkout process can deter customers.
- Mobile Optimization: Ensure that your custom fields are responsive and display correctly on mobile devices.
- Testing: Thoroughly test your checkout process after adding custom fields to ensure everything is working correctly. Test different browsers and devices.
